Don't make a Paycheck for someone getting No Pay. It's not 0 hours. It's No Paycheck, entirely. Do not Checkmark that employee.
The "reminder" is because you set a Schedule for pay period and pay dates, and the system is trying to help you by being the Calendar reminder function as a helper tool. That is different than the question of who is Paid, this time, and who is Not paid, this time, because they didn't work this Pay Period.
